Henry Gannett (August 24, 1846 – November 5, 1914) was an American geographer who is described as the “Father of the Quadrangle” which is the basis for topographical maps in the United States.

Known as the Father of Government Mapmaking, In 1884 he published his first Dictionary of Altitudes which listed all known survey altitudes in the United States as well as the source of the survey. He was to persuade various organizations doing the surveys including the railroads to begin using similar datums so the data could interconnect.
